Head compartment

In these photos this is far from being done; but I was just fooling about with the camera and took some photos of the head area to record progress.


This is the head sink, which, as all H25 owners know, the boat did not originally come with.

The stainless-steel basin came from an old Chris-Craft; I bought it on eBay for $19.00.  Its drain goes through the forward bulkhead-- to get out of the foot area-- and then to a trap and down to the drain seacock.

The after portion of this countertop (to the left) lifts up for access to a 4-inch-deep compartment above the foot of the bunk.  The two openings outboard of the sink are for toiletries and towels.  The little mahogany stick on the forward bulkhead, inside the locker, is the cleat for the shelf in there.  The shelf divider is sitting against the hull.

I put the tissue dispenser in there to calculate the space for it; but I certainly won't rely on a cardboard tissue dispenser to be kept in the head, under the large foredeck hatch, aboard a 25-ft boat!

There is no headliner or hullliner in place in this photo.  The trim is not installed here either.

The wiring isn't really this messy-- it's just dangling down from the connections block above this doorway where the spar wiring enters the cabin and the cross-cabin circuits pass by.  When it is connected properly you won't see the danging bits in and out of the lockers.


This Wilcox-Crittenden Head-Mate toilet was given to me by a guy called Bill who was working on his friend's boat in Hancock's Harbor, NJ.  I saw it sitting outside the boat on a Sunday and left a note on it: 'If you are getting rid of this toilet, call me and I'll take it.'  The guy called me as soon as he returned to the boat.  It pumps perfectly well-- they must have been switching to either a larger bowl or just an electric one.  The intake/flush lever is a little rusty; that's all I can find wrong with it.

I had intended to mount my existing 'Frankentoilet' with the crossover sanitation pipe underneath this blue shelf; so the shelf is mounted a little higher than it would otherwise be.  Unfortunately this toilet's pump doesn't mount on the level; it mounts at a slight angle (like a modern Jabsco) on an angled flange on the crossover pipe.  So I can't mount this pump on the shelf, with the crossover pipe underneath, because it won't sit flush.  I have no idea why Wilcox did it like this.  I really wish I were reusing the original Raritan Compact Mk I; but this is similarly 'retro' and works fine-- and best of all the price was right.

The two little openings under the shelf are meant for access to the bolts; and this was supposed to accommodate the crossover pipe underneath so these would allow for cleaning out as well.

Behind the toilet the black ring is a Starboard trim piece around the exit pipe (PVC) leading to the holding tank.

The all-plastic Rubbermaid tool box is actually in its intended place-- this V-berth area has become a true forepeak, having room for only one to sleep but getting equipped with a tool box, workbench, hanging locker, microwave oven, plenty of outlets for charging cordless tools and possibly also a fresh-water supply tank for flushing the toilet. The holding tank is underneath, with most of the plumbing and all but one of the boat's through-hulls.  And that's in only the aftermost 26 inches of it! [wink]

The mahogany in the foreground is the backup to the compression post, underneath where the maststep really is.  It's a piece of the stock I cut for the cabintop handrails, but here it is solid except for only one hand hole (through which the vacuum cleaner's cord is running).  I gauged this hand-hold for someone sitting on the potty and only after installing the stick I realized that the head door's latch has to go at the very same elevation-- so when you reach through it you will stub your fingertips on the edge of the latch plate.  Oh, well.

At the time this was taken the lockers behind the toilet were taken up with the stereo, the outlet strip and the lift-out panels for all the lockers about the boat.

The bronze Barlow selftailing winch (vintage 1977) is a leftover from Warren Luhrs' C44 cutter and served as a doorstop in my mother's bathroom for about 20 years.  It's now slated to be the foredeck-mounted anchor-rode winch for a first-generation Hunter 25 called Diana.  Funny how things turn out!


Here is an 'aerial' shot of this space, minus the toilet, taken from the foredeck hatch opening. 

The door jamb, to the right, was excessively tedious.  It is a T-section and has to fit a very awkward three-sided space and accommodate the natural crookedness of the boat as-is.  It turns out that the face of the head's sink cabinet (side of the port-side berth's footwell) is neither in one plane (it's twisted) nor parallel to really... anything.  Fitting delicate mahogany (the lower portion of that stick is 5/16" square) to a crooked boat is an exercise in near-futility.  But I got it to fit!


The threshold of this doorway is somewhat more robust.  If it appears crooked, it's because the main bulkhead of the boat is not square to the centerline.  Believe it or not that threshold is in the only place it can be to make the (not yet built) door work.

I still have to countersink those screw-holes to fit them with plugs; but I'm keeping it as removable in case something happens with the door later.

The rough plywood sole is only temporary.  The finger-hole, however, will be in the finished mahogany panel.  It's the drain for the space, as there'll be a shower hose here too.


The black square is the pedal for the Whale Gusher foot pump for the head sink.  It feeds from only the port tank, however, despite being likely to be the most-used water source in the boat.

In the foregound (top right of photo) you see the coaming for the foredeck hatch, not yet varnished.

I like the deep-blue/white/black/stainless/mahogany decor theme of this boat.  It's bright, cheerful, nautical and traditional.

Removing holes from aluminum spars

One vital consideration concerning aluminum spars is that they derive all their strength from skin stiffness.  Aluminum can and will bend; but as the molecules shift about it's important to not give them anywhere to go that they should not be.  This means all extra holes in an aluminum spar will weaken it.

My boat came with the then-common 1970s slab-reefing system consisting of a genoa track mounted on the boom, a cheek block mounted on a slide, and a Cunningham hook above the gooseneck.  The single-line reefing system as depicted in the Schaefer catalogue and elsewhere makes infinitely more sense, not only for sail trim but for simplicity and even safety.  Properly located, the parts of single-line reefing will contribute to a very efficient sail shape for the reefed sail and give one the ability to effect the reef from only one place-- in my boat's case, the safety of the bridge deck and main hatch.

To remove the parts of the old system required the filling of some two dozen holes on the boom and elsewhere.  Certainly one could weld these and have an excellent-- though expensive-- reconditioned boom.  Honestly I never thought of that; but I knew I'd have to fill them somehow.

Then Jeremiah, in the shop, suggested just using aluminum screws, threading them into the holes, and breaking them off to file them smooth.  The sheer simplicity of this idea just blew me away.  After all, so long as the holes are filled with something that can't shift-- thus prohibiting the molecules from moving too far-- it does not matter how you fill them.

Amazing Grace, the C48, came into the shop for a refit and I got the job of preparing the booms for refinishing.  As part of the job the aluminum screws were ordered; as soon as the necessary holes were filled I took off with the broken-off bolts and reused them all on my own boat. After all they only need to be long enough to thread into the wall thickness of the spar.


This first photo is not great, owing to glare; but the aluminum screws sticking out of the side of the boom (spar to the left) are visible. Most of these were for the reefing track.

The black tape marks where the sheetline bail will go.


In this photo you can see where a few of the screws have already been broken off.  I sawed most of the way through each one and then bent them with pliers to snap them off.  These screws are 1/4-20 thread.  They can break off when you're about 2/3 through them with the hacksaw.  The best idea is to saw them as close as possible to the surface of the spar-- but you'll have to choose one thread of the screw as the hacksaw blade will choose one for you otherwise.
The red stuff is Loctite 'permanent' (not my blood; that's elsewhere).  A caveat: the Loctite will work only if the hole is the right size for the screw and decently threaded.  Don't count on the Loctite to fill gaps (or even to stick if there are gaps).  If there is too much play, you can use epoxy (perhaps with a little filling compound) instead.


Here is the side of the boom after the screws were broken off and sanded over.  Can you see where they were? --for you certainly can't feel where they were with your hand.












Here is a close-up of the side of the boom, with a better view of the filled-in screw holes (silver circles).  I sanded these by hand-- 80-grit production paper takes the nubs down quickly and easily.  You will see a trace of greasy-looking aluminum residue following your sanding-- this tells you that you are actually sanding the end of the screw.  When you see the surface of the boom going silver you've come to the end (as you see how I hit it here).

I changed to 120 grit and then to 220 to polish these off.  As I will shortly be applying etcher, primer and paint I'll be able to further fair these places, should they need it, at any point during the future stages.




I filled the holes for the winch bases on the mast as well.  Since those holes were a bit too big to accommodate 10-24s any more, I drilled them all out to 1/4-20 (I should have used 12-24 but didn't think of it!).  In installing the winch bases on the mast again, to avoid running afoul of the old (now filled) holes, I can relocate them.  The open holes shown here are the new ones drilled to reuse the old mast bases in new locations.

(The pole in the back is the fence, not the spreaders!)

Internal pole lift

Since this boat is so small, it's unlikely I'll ever have a proper whole-cockpit awning without setting it over the mainsail cover.  So when in the ICW or anywhere that calls for more powering than sailing, I won't have the opportunity to set any sail to assist the motor other than the jib itself, which is too far forward to allow the boat to balance under the one sail alone.  What's needed is a smaller sail more centrally set, fore-and-aft, that can pull reasonably well on most points of sail in light air... like an inner forestaysail.  And, more importantly, it will also serve to take over when/if the motor fails.

This is more important than most people realize.  A prudent mariner should never enter a dodgy or unfamiliar harbor with the mainsail cover drawn and snapped closed and the headsail bagged or lashed to the deck.  (I know-- most people will claim that having a roller-furling headsail resolves this.  But the point still bears consideration.)  In such a state, if you were to suffer an engine failure you'd be hard-pressed to get anything up and drawing air before you crashed or went aground.  It's a matter of simple seamanship.

I've had the idea to have a regular spinnaker-pole lift that can also be used as a halyard for a small jib, what I call the 'canal sail', something small but useful to assist the motor, provide safety and redundancy and maintain steerage in freaky currents and conditions.  I decided to use the former winch mount on the starboard side of the mast and to reuse the old Seaboard halyard winch for this.  (The port side gets another winch base and a Lewmar #6; more on this later).


This exit block came from DAMCO (Dwyer Aluminum Mast CO.)  These people are the very best in the business, helpful, sensible and economical.  This block cost $26.00 and handles 5/16" line (actually 3/8" would fit but oughtn't be loaded to capacity).  A Schaefer one is over $90.00.  I cut this hole and mounted this thing using tapped 10-24 screws; it will get removed when it comes time for paint and then reinstalled.

I calculated the location using an original 1973 blueprint of this boat's sail plan which Skip Moorhouse, sailmaker and first owner of Hunter 25 hull no. 1, let me inspect.  Assuming a theoretical inner forestay about 3'9" aft of the headstay, it would land on the foredeck about 4' aft of the headstay plate.  So the place for this block is about 9'7" down from the top of the mast.  In this way I could, if I chose to, fit a tang here to accommodate an inner forestay and running backstays and so configure this little boat as a bona-fide cutter.  I just figure if you're going to install something like this, you might as well make some sense of it, if only in theory.

At the other end I have to add an exit plate on the starboard side, rather high up in order ti lead it down to the winch.  The existing two exit plates are for the two main halyards.

In reusing the old Seaboard winch I have to keep in mind that the handle for it is a hexagonal drive, unlike modern standard square-drive winches.  Apparently in the early days of top-action winches (about 1968-1978), there was no standard top-drive handle format (sounds eerily familiar to the development patterns of other technology!).  Fortunately I have one of these handles; though it might have been easy enough to just use the Seaboard winch as a snubbing winch and use arm strength to cleat it tightly each time-- it's only a pole lift on a 10-ft pole.  But now I have to ensure that I have room on the spar for two handle holders, one for each handle.

Some inconveniences are beyond counting

I once told my young brother-in-law, as he was building some plastic model airplane and complaining about glue on his fingertips, that to do a good job sometimes you have to love your project more than you care for your self.  This is especially true when it comes to convenience-- after all, most of the things we love are patently inconvenient.  And yet we pursue them anyway; and in this pursuit is how we acknowledge their value to us.


This photo is not great; it's intended to show the nice fat mahogany splinter I got in my foot.  (How? --I wasn't even barefoot.)  In this one week I got this splinter and another as well, tore my fingertips on a jigsaw blade (it was not running), jammed the meat of my hand in the drill-press chuck and mysteriously gashed my leg which bled all over the project in process.

The West Marine sticker is on my daughter's laptop.






Here is the top of the cabin, with no hatch or hatch shroud in place, the day I was fastening down the new hatch-slider rails.  The green tape along a piece of wood is a dam to keep epoxy from coursing down the side of the cabin and over the windows (already let that happen once, so never again!).  I had noticed a stickiness whenever I was kneeling a certain way but in the semi-mad rush to get the sticks into position and screwed down I attributed it to something stuck to my leg.  Only when I was done the most urgent part of it did I happen to notice the red stuff, which I then concluded was blood.

That's the foredeck's hatch coaming in the distance.  At the time of this photo the hatch shroud was being used to cover up that opening-- that's it even farther beyond.

Below you can see something of the main cabin, the compression post, the settee and head trim, and whatnot.


So I took this photo downwards at my leg, probably just to record the solution to the mystery.

Here I am standing up on the quarter berth, my other foot on the ladder step.  The quarter berth is (at this time) the current lumberyard.  The gap below my foot is the 'wet locker,' the one place inside the accommodation that goes straight to the hull skin itself.  Over this I would like to make a panel of slats, like the white-pine ceiling we make for C44s.  On the side of the ladder, behind my leg, goes the stainless-steel double hook to hang up wet foulies.  On the teak cabin face behind me is already another of these hooks.


You can see the cooler under the bottom shelf of the ladder; its cover is accessible when you lift the shelf.  A Fastpin stuck through a hole in the ladder side holds it up.  It's made so that if one should descend the ladder while the shelf is up the shelf won't stick out so far so as to catch a heel and break off-- although it does mean there won't be a second shelf in place for the one coming down.

Also two sections of the three-part cabin sole are visible here.  At the time of this photo the center section is just rough plywood-- it'll be varnished mahogany later.

Cockpit-seat lockers

These are some older photos that never got posted under any specific topic.  In most cases there has been much progress since these were taken.


1. Here is a view into the port side locker, what used to be the fuel-tank locker.  As I have said before, this area was so soggy when I acquired the boat that I removed the bulkhead and shelf with bare hands-- really; no tools needed!  The bulkhead was formerly under the drip rail to the right.  I made a new bulkhead about 8 inches farther aft, to make the quarter berth about 6'4" or 6'5"; the foot of it is under this shelf, which, with a fiddle installed, will hold winch handles and the like.

In this photo the shelf is holding a plastic bulkhead vent fitting which I may end up not using and a length of SS angle intended for the backstay's backing plates (since substituted with aluminum).

Outboard is a little box/shelf I made to hold quart cans of paint, solvent, 2-stroke oil, and whatever.  It drains into the area farther inboard.

I really hate black 5200-- it always looks unclean and messy somehow.  But it's what I had; and this will all be painted in white Bilgekote.

The port-side battery's breather tube comes up through the box/shelf and extends up like a snorkel to within a few inches of the underside of the coaming (the PVC coupling seen on the shelf is for that).  The battery is under the main-cabin settee.

The after bulkhead replaces the one that was there holding up the fuel-tank shelf.  The 3" hole will accommodate a ventilation tube leading from the Dorade box (after of the tiller head) to the foot of the quarter berth.  This will be PVC, as it should be rigid to keep from being damaged when stuff gets dropped or thrown into this locker.

You can see the bodged-up job the PO did in increasing the size of the openings in the hatch's drip rail.  The real reason he had such leaks is because he had cut out the drip rail itself along the outboard side of the hatch to accommodate overly-big hinge bolts.  I patched this, not prettily, but adequately to lend it strength.  This will get sanded and reshaped prior to paint.


2. This is a look straight down at the starboard-side locker.  At one time the fresh-water tank was under a platform at the forward end of this space.  It was not there when I acquired the boat.  My new fresh-water tanks go under the main-cabin settees.  I fitted this shelf in here to lend stiffness to the hull the way the quarter berth does on the other side.  All major flats and verticals should be structurally bonded to the hull-- they all help.

For access under this shelf I made two lift-out panels.  I really cannot think of what I would put down there, as the top of this shelf will be full of things like life jackets, mooring line, fenders and a folding bike.  The inboard opening without a cover (left side of the pic) is for the engine-starting battery.  A standard-sized battery box fits into here with its ear handles holding it from sinking all the way through.  Of course this will get screwed in place-- and a strap fitted over the cover when the battery is installed-- as well.

The little block of mahogany is a step I made on top of the edge of the stiffening rib so that, for the many times I have climbed down this hole for access under the cockpit and aft, there is something to step and lean upon that is more substantial than the knife-edge of a piece of 3/8" plywood.  (My back is grateful for this!)

Under the cockpit at the lower edge of the photo you see the black plastic (Tempo) fuel tank, which is 11.5 or 12 gallons.  It sits on a plywood shelf, the edge of which protrudes a bit this side.  As it is located, the tank is about one inch off center but otherwise fits perfectly, with all access points at the after end for vent, sender, feed and fill.

The openings in this hatch's drip rail were enlarged too but not as clumsily as the ones on the port side; I filled and faired these as well.


3. This is a look from inside the starboard-side locker, looking forward.  You see the two lift-outs and the hole for the battery box.  All of this has received one coat of Interlux Bilgekote; it'll get another coat before it's done.

The things in the forward corner are a brass tube, which will be installed in that bulkhead, down by the hull, to admit bilge water from this compartment to where the bilge pump is, and the ends of the PVC tubes that lead to the electric and manual bilge-pump pickups.  I made this section of them in PVC because it would be nightmarish to thread any replacement hose through this route once the boat is done.  PVC can be assembled in pieces, in place, so even in the unlikely event that the PVC might fail it too can be replaced after being hacksawed out.  From this point hose, with check valves to avoid backfill, will lead towards the transom outlets.  The vertical PVC tube mounted on the plywood block is the starboard-side battery's breather which extends up to within a few inches of the underside of the deck.  The battery is located under the settee berth.

The wooden bulkhead is the back side of the teak plywood bonded to the inside of the cabin back.  It extends down below the galley counter back here and provides a surface to which to fasten wiring and other stuff.  In this plywood will be fitted the on-off switch for the engine-starting battery, so one can reach down to the galley from the main hatch and switch it on or off.  Also the wine lockers will be mounted in this bulkhead (more on that later).

The long skinny shelf along the side of the cockpit (to left in the photo) will get a varnished-mahogany fiddle to hold stuff (mainly because I have plenty of countertop-fiddle stock).  This shelf was installed to seal the under-cockpit locker from potential fuel fumes (the tank is out of view just to the left of the camera).  This whole compartment gets vented via a Rule #140 blower and a hose leading to the Dorade box.

Just forward of the drip rail (angled feature at top left in photo) in the cockpit side will be mounted the throttle and shift for the motor; so those cables will run straight towards where I was holding the camera here.  Also the Whale manual bilge pump gets mounted in the cockpit side just to the left of the camera.
